What I'm looking for

I’m looking for backend or platform roles where I can build scalable systems and ship AI-powered retrieval/LLM features, collaborating on production-grade architectures, strong DevOps practices, and real client impact.

I'm an AI Engineer and Backend Engineer with 4.7+ years of experience designing and building scalable backend systems, enterprise SaaS platforms, and production-ready AI applications using Python, FastAPI, Node.js, TypeScript, and Azure.

At BigDev Technologies, I developed enterprise compliance platforms for global clients, taking ownership of backend architecture, REST APIs, cloud deployments, CI/CD pipelines, and production support. Alongside backend engineering, I built Generative AI solutions powered by Azure OpenAI, OpenAI APIs, LangChain, LangGraph, Retrieval-Augmented Generation (RAG), semantic search, Pinecone, and Weaviate to automate document intelligence and enterprise knowledge retrieval, significantly reducing manual effort and improving search accuracy.

My experience includes developing AI agents, prompt engineering, tool calling, vector search, embeddings, workflow orchestration, and integrating LLMs into enterprise applications. I have built secure, scalable systems using Azure AD SSO, OAuth 2.0, JWT, RBAC, Docker, Kubernetes (AKS), Azure DevOps, and CI/CD, with monitoring through Prometheus and Grafana.

I'm passionate about building production-grade AI applications that solve real business problems. My current focus is on LLMs, Agentic AI, multi-agent systems, RAG architectures, AI automation, MCP, LangGraph, and intelligent workflow orchestration, while continuing to design scalable cloud-native backend platforms. I'm looking for opportunities where I can build next-generation AI products and help organizations adopt Generative AI in production.
